IMPROVEMENT IN MOTORS FOR SEWING-MACHINES.

Specification forming partof Letters Patent No. 189,624, dated April 17, 1877; application filed March 9, 1877.

To all whom it may concern Be it known that we, JAMES HAWORTH and WILLIAM H. NEWELL, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Motors for Sewing or other Machines. 850., which improvement is fully set forth iii the following specification, reference central tube, through which the shaft of the wheel passes, so as to prevent any portion of the water, in its passage to or through the chute, being forced by the head of water into the stuffing-box, as hereinafter more fully de- There is a check-valve in the branch pipe, for regulating and cutting off the supply of water. The stem of the valve is provided with an arm, to which a spring is connected for closing the valve, and for opening the same a rod is connected with the 'arm and a treadle, as hereinafter fully described.

A is a cylindrical case, containing a revolving wheel and stationary chute. It has a branch, A, provided with a female screwthread in its outer end, for connecting it with a feedpipe, which takes its water from a street-pipe, to get the force of the head of water.

The branch is on an incline, as represented, to incline the water directly to the wheels.

The cylinder has a central shaft, B, which passes through the stuffing-box G in the upper end of the cylinder. The lower end of the shaft, which is provided with the water-wheel D, turns in the step E. The middle part of the shaft revolves within the hollow shaft or tube H, the upper end of which is fast to the stuffing-box O, and permanently connected with the lower end of the tube is the permanent chute I. The wheel fits closely upon the revolving wheel D, so as to prevent any back flow of water which would force its way to the stuffing-box.

Another advantage resulting from this arrangement is, that the chute is quickly placed in position in the cylinder A, and is held there by means of the tube, without any additional fastening.

From the stuffing-box is projected the pedestal J, which has a bearing, a, for the upper end of the shaft B. The pedestal is made fast to the stufling-box for the sake of simplicity, permanency, and cheapness.

On the outer end of the shaft are the differential pulleys K K, for connecting it with a sewing-machine by means of a band:

L is a check-valve in the branch A, for regulating and cutting off the supply of water. The stem 1) of the valve passes up through the stufling-box G, and has an arm, 01, for operating the valve.

M is a spring, the heel of which is fastened by means of screws to the branch A, as seen in Fig. 2. The spring has a turn around the branch, and to its resilient end is connected one end of the link N, the other end of which is connected to the arm (1 of the valve-stem b,

whereby the valve is closed. The end of the arm has a hole, 6, by means of which one end of a rod or wire is connected, the other end being connected with a treadle, for opening the valve for the passage of water for operating the sewing or other machine.

The motor may be used for other purposes, when desired.

We claim as our invention- 1. The combination of the hollow shaft or tube H with the stuffing-box O and the stationary chute I, the end of the shaft being permanently connected with the stuffingbox and chute, substantially in the manner and for the purpose set forth.

2. The combination of the check-valve L, having a stem, b, and arm at, the spring M, and link N, with the induction-branch A, substan tially as and for the purpose set forth.
